"#ReadyPlayerOne is classic Spielberg fun! What a blast, can't wait to see it again. Rewards repeat viewings. Tons of great references, visuals and heart," wrote Robert Rodriguez. "So kick ass it blew the speakers!"

Yep, despite the screening being hit with some technical difficulties, people were generally thrilled...

Bit of technical difficulties during climax of #ReadyPlayerOne sound cut out and it stopped. Don't they know all they need to do is take the cartridge of the film out and blow on it!? Duh! ...Seriously though this film is a gamers dream! Kick Ass so far!

The sound just completely cut out at a huge moment in the climactic last act of #ReadyPlayerOne and people in the audience started making their own pew pew pew sounds, movie is now completely paused for Ready Re-player One lol I'm here all night folks (maybe literally) #SXSW

AHHHH READY PLAYER ONE!!!!! Haven’t felt that sense of childlike wonder since JURASSIC PARK. This film lacks the terror of that film but the sense of joy is overwhelming. This film is love. #sxsw#sxfilm#sxswfilm#ReadyPlayerOne

#ReadyPlayerOne is classic Steven Spielberg. It’s got the references, the ferocious effects and the great ‘80s soundtrack, sure, but also the charm, the heart, the humor and a fantastic Alan Silvestri score. I loved it & so did this #SXSW crowd. Be excited for it! pic.twitter.com/xwPOGwXDxd

I don’t know if I have ever seen a #SXSW crowd cheer on a movie the way they just cheered on #ReadyPlayerOne. We haven’t seen this Spielberg in a long time - it’s just pure entertainment and it’s hard not to watch it without a dorky smile on your face the whole time

"A rollicking adventure through worlds both bleak and fantastic, Steven Spielberg's Ready Player One makes big changes to the specifics and structure of Ernest Cline's best-selling novel but keeps the spirit and level-up thrills intact."

"Ready Player One is a relentlessly entertaining movie. If you are a fan of the genre, get in line. Like all sci-fi fans, I look forward to seeing it, again and again, to earn its many Easter Eggs and ultimately own the OASIS myself."

Ready Player One centres on Wade (Tye Sheridan) and his girlfriend Samantha (Olivia Cooke), who unleash a revolution in the virtual reality world OASIS as the real world crumbles around them.

Ready Player One is released in UK cinemas on March 28, and in US cinemas on March 29.
